Ionic equations

Write the following as ions as appropriate. Include state symbols:

1) Mg(OH)2(aq) 2) HNO3(aq) 3) Mg(NO3)2(aq) 4) CaSO4(aq) 5) 2Al(NO3)3(aq)

Mg2+(aq) + 2OH-(aq) H+(aq) + NO3-(aq) Mg2+(aq) + 2NO3-(aq) Ca2+(aq) + SO42-(aq) 2Al3+(aq) + 6NO3-(aq)

 

Write the following as balanced ionic equations:

6 Ca(OH)2(aq) + H2SO4(aq) CaSO4(aq) + 2H2O(l)

OH-(aq) + 2H+(aq) H2O(l)

7 SrCO3(aq) + 2HNO3(aq) Sr(NO3)2(aq) + H2O(l) + CO2(g)

CO32-(aq) + 2H+(aq) H2O(l) + CO2(g)

8 Al(s) + H3PO4(aq) AlPO4(aq) + 1.5 H2(g)

Al(s) + 3H+(aq) Al3+(aq) + 1.5 H2(g)

9 AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq)

Ag+(aq) + Cl-(aq) AgCl(s)

10 Dilute Nitric acid is added to a solution of aluminium carbonate

CO32+(aq) + 2H+(aq) H2O(l) + CO2(g)

11 Dilute sodium hydroxide is added to a solution of iron (III) chloride. A red precipitate of iron (III) hydroxide and sodium chloride solution is made
